Evaluation of a Novel Pancreaticojejunostomy Technique for Pancreaticoduodenectomy

The recruitment status of this study is unknown. The completion date has passed and the status has not been verified in more than two years.

Pancreaticoduodenectomy is a surgical procedure for removing cancer in the pancreas, the bile system or the duodenum that is associated with a high rate of complications. The study wants to investigate whether a new technique to reconstruct the joint between the pancreatic gland and the short bowel can reduce the rate of severe complications after this complex surgical procedure.

Primary Outcome Measures:
  • Clinically Relevant Postoperative Pancreatic Fistula [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 2 weeks ]
    Postoperative pancreatic fistula as defined by the International Study Group of Pancreatic Fistula

Secondary Outcome Measures:
  • Associated postoperative morbidity [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 2 weeks ]
    Postoperative pancreatic fistula and abscesses or fluid collections adjacent to the pancreaticojejunostomy constitute a morbidity event; pancreaticojejunostomy-associated morbidity.

Other Outcome Measures:
  • Severity of postoperative complications [ Time Frame: participants will be followed for the duration of hospital stay, an expected average of 2 weeks ]
    The severity of postoperative complications as classified by the classification system of postoperative complications adopted for pancreatic surgery.

Estimated Enrollment: 120
Study Start Date: September 2011
Estimated Study Completion Date: September 2015
Estimated Primary Completion Date: April 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
No Intervention: Conventional anastomosis
Conventional anastomosis: The pancreaticojejunostomy is carried out in a traditional way according to "Cattel's duct-to-mucosa technique".
Active Comparator: Novel anastomosis
Novel anastomosis: This the active comparator to the conventional anastomosis. A new pancreaticojejunostomy technique is used for the reconstruction. The pancreas is intubated into the jejunum.
Procedure: Pancreaticojejunostomy technique
The anastomosis between jejunum and remnant pancreas has a pivotal impact on the incidence of postoperative pancreatic fistula. by this novel technique the remnant pancreas is intubated into the jejunum without extensive manipulation.
Other Names:
  • Pancreaticojejunal anastomosis
  • Intubating pancreaticojejunostomy
  • Dunking pancreaticojejunostomy
  • pancreatojejunostomy

Detailed Description:
Pancreaticoduodenectomy is a complex surgical procedure for radically resecting tumors in the pancreatic head, distal bile duct or duodenum. Postoperative pancreatic fistula is the main contributor of severe postoperative morbidity after pancreaticoduodenectomy. Characteristics of the pancreatic gland like soft pancreatic consistency and small pancreatic main duct predispose for the postoperative fistula development. In high risk patients, the risk of suffering from associated postoperative morbidity is 50 percent which is considered unacceptable high. The aim of the current trial is to investigate whether a new anastomosing technique for the pancreaticojejunostomy can reduce the incidence of associated postoperative morbidity in patients undergoing pancreaticoduodenectomy.

Inclusion Criteria:
